How Is My Air Conditioning Sized?

A new air conditioner is a significant purchase, and involves a number of considerations before pulling the trigger. You may not be aware of all of them, but they can have a serve impact on your new purchase, and require the services of a professional technician to get right. This is particularly important for residents of Dover, DE, and surrounding suburbs: facing another hot summer and requiring a new air conditioning system to function as efficiently as possible. In order to ensure that, you need to have your air conditioner properly sized to your home. By “sized” we mean the relative cooling power of your new unit, instead of the physical sized. “How is my air conditioning sized and why is that so important?” you ask. Let us provide you with a few answers.

The Goldilocks Rule

Sizing is important because of what we like to refer to as the Goldilocks rule: your air conditioner should be neither too large nor too small, but just right for your space. If it’s too small, it won’t be able to cool the air adequately. If it’s too large, it will cool the air too quickly, and engage in short cycling throughout the day: adding to your wear and tear in the process. Only the right-sized air conditioner will do the job as intended without costing you in higher energy bills or increased risk of repair.

How Proper Sizing is Determined

Proper sizing starts with the square footage of your home, which is roughly 12,000 BTUs (British Thermal Units) per hour for every 500 square feet of space. To that, the technician will factor in a number of additional variables, such as the amount of insulation in your home and home much sunlight is allowed in through your windows.

Those equations require training and practice to solve successfully. That’s why you should call the experts at Atlantic Refrigeration & Air Conditioning to install your system. We know how to size air conditioners and our trained professionals are dedicated to doing the job right!
